Abstract:
Signaling-regulated transcription factors (TFs) orchestrate the developmental and differentiation trajectories of cells and their activation states. Understanding TF activities at the single-cell level represents a formidable challenge. Single-cell multi-omics technologies now measure different modalities such as RNA, surface proteins, and chromatin states. Moreover, emerging spatial technologies offer highly multiplex profiling of RNAs and proteins, while preserving the spatial context of the tissue. Consequently, there is a tremendous need for computational methods to integrate these measurements and infer the underlying cell type- and state-specific transcriptional programs. In this talk, I will present our computational frameworks for delineating context-specific regulatory programs based on single-cell omics and spatial transcriptomics datasets. These frameworks have the potential to fill a significant gap in knowledge by defining cell context-specific regulators driving cellular identity, as well as discovering new targets and approaches for advancing therapy.
